A new drawing called Reflection IV, 2016 donated by Mr Gormley sold for £2,700.

Hattie Allsop from the charity said the results had been “amazing”.

About 200 artworks were listed in the The Big Heart auction to raise funds for the small Minchinhampton-based charity.

Many of the pieces were donated after an appeal by Los Angeles stylist Dave Thomas who grew up in Gloucester and whose aunt was looked after by the hospice.

Mr Thomas said: “(Boy George) did that back stage at the Hollywood Bowl when he was performing with the LA Philharmonic Orchestra so it is quite a special one.”

Ms Alsop said the auction had raised £15,000 for the charity but an LA buyer had offered another £4,300 if Boy George would replicate his pen and ink sketch.
